IMPROVEMENT IN INDIA-RUBBER SHOES.

Specification forming part of Letters Patent No. l 11.962, datedFebruary 21, 1871.

To all whom it may concern:

Be itknown that we, CHRISTOPHER MEYER, of the city, county, and State ofNew York, 'and JOHN EVANS, of New Brunswick, Middlesex county, NewJersey, have invented a new and useful Improvement in India RubberShoes; and we do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the accompanyingdrawing, forming a part of this specitication.

My invention relates to the strengtheningribs employed upon the uppersOf india-rubber shoes; and consists in an improvement which will behereinafter described, and subsequently specified in claim.

Figures 1 and 2 represent plan views of two modifications of these ribs,and Fig. 3 a sectional view of forming-rolls with the plastic substancepassing therethrough.

A A in Fig. 1 represent plain ribs inclosing a space in configurationsimilar 'tothe openings in the uppers of Ordinary rubbers. b is animitation thread passing around each rib. A A in Fig. 3 represent theribs arranged in the form Of a sin gle ornamental buckle. B in Fig. 2represents rolls, of which the lower is plain and the upperlongitudinally ribbed. a a, represent the ribs formed from the plasticrubber as it is carried through the rolls; and it will be Observed thatthey are not corrugations, like the strengthening-ribs used upon metal,but a thickening up of the substance in certain lines or directions.

The process through which the material passes to bring it into the formrequired is as follows: The mass of plastic rubber is forced into 'theopenin g between the molding or shaping rolls, and drawn Out into asheet with the ribs completely shaped. 1t is then vulcanized and made upinto the shoe or sandal.

We are aware that two sheets have been employed with openings in theouter while the inner sheet is preserved entire, and that in this case astrengthening-cord has been rolled into the plastic rubber and securedby vulcanization.

We are also aware that strengthening-ribs have been formed of elastichalf-round strips cemented to the surface of the upper.

Hence we desire distinctly to disclaim either of the above modes oftransversely ribbing the uppers of rubber shoes and sandals; but

What we do esteem to be our invention, and desire to secure by LettersPatent, is-

One or more transverse ribs in rubber shoes Or sandals, formed bythickening the substance itself in the lines or directions thereof whilein the sheets by means of rolling-dies, as and for the purposedescribed.
